“闯关式”开放实验在生物技术专业实验教学中的实践与探索

The practice and exploration of"breakthrough"open experiments in the experimental teaching of biotechnology specialty

生物技术专业的实验技术具有步骤多、连续性强、需要时间长等特点,技术手段日新月异。然而现有的实验教学模式尚存在内容不满足就业、不能做到因材施教、不能与时俱进等弊端。本研究将“闯关式”教学模式运用到生物技术专业实验课程中,采用“必修(教学大纲)+选修(闯关式)”相结合的实验模式,结果显示大多数同学最终均能达到通关要求,学生对“闯关式”开放实验教学模式评价较高,认为其能激发积极性,促进深入学习,提升实验技能,拓宽视野,增强综合素质,为未来深造与就业增添优势。调查表明,生物技术专业实习生大体上认为自己素质技能良好,能胜任工作。同时,实习点带教教师对生物技术专业实习生的综合素质、知识素质和专业技能均表示满意。在生物技术专业实验课程中引入“闯关式”教学模式,不仅能显著提高学生的学习热情,还能有效拓宽他们的知识视野,培养他们的创新思维和知识应用能力,从而为学生今后的实习、工作以及考研等奠定坚实的基础。

The experimental techniques in the field of biotechnology are characterized by multiple steps,strong continuity,and lengthy time requirements,with technological methods constantly evolving.However,the current experimental teaching models still have drawbacks such as not meeting employment needs,failing to tailor teaching to individual students,and not keeping pace with the times.This study applied the"breakthrough"teaching model to the laboratory courses of the biotechnology major,adopting a combination of"required(syllabus)+elective(breakthrough)"experimental models.The results showed that most students could ultimately meet the requirements to pass the levels,and they have a high evaluation of the"breakthrough"open experimental teaching model.They believed that it could stimulate enthusiasm,promote in-depth learning,improve experimental skills,broaden horizons,enhance comprehensive qualities,and provide advantages for future further studies and employment.Surveys indicated that biotechnology interns generally considered themselves to have good quality and skills,being capable of handling their work.At the same time,the instructors at the internship sites express satisfaction with the comprehensive qualities,knowledge qualities,and professional skills of the biotechnology interns.Introducing the"breakthrough"teaching model into the laboratory courses of the biotechnology major not only significantly enhanced students'enthusiasm for learning but also effectively broadened their knowledge,cultivated their innovative thinking and knowledge application abilities,thereby laying a solid foundation for their future internships,work,and postgraduate entrance examinations.
